Recommendation of out door tomatoes

Garden organic have 6 large grafted plants for £15 says they are blight resistand and good outside. Not sure what postage would be or if you would get 20% off with Veggies code.

Mark you really need to know, I don't like spending money, so £15 is way beyond what I would part with

I knew that when posting but it is a bit late now to be sending off for seeds to sow next week for this year. And someone else, not so frugal might think it worth it as an experiment. You might even get more than £15 worth of tomatoes off them if they arrive in good condition. It would be a challenge to get your moneys worth anyway.
